TEMPORARY BINDER on LOOSE-SHEET HOLDER.

To all whom it may concern:

Be it lmown that I, JOHN PAx'roN PETTY,

1 a subject of His Majesty the King of England, residingat Reading, Berkshire, England, have invented certain new and useful Improvements in Temporary Binders or Loose-Sheet Holders, of which the follow- 7 ing is a specification.

This invention relates to temporary binders or loose sheet holders and is particularly directed to binders or holders of the kind in which a pair of sheet or the like clamping bars, associated with apairof coversand a telescoping back strip aredrawn together to clamp the sheets by means comprising a rotating element such as a rod or spindle located longitudinally of the clamping bar.

M By and in accordance with the present in- .Vention a back or loose strip telescoping in chambered coversof the binder is fitted to the binder in such manner that it is positively adjusted simultaneously andin accordance with the adjustment of the clamp- 1 ingfbars through the medium of the rotating element and an endless band operativelyconnected therewith and attached to the back strip so as to move the-attached end of the back strip backward and forward according to the direction of rotation of therota'ting element.

In order that the invention may be clearly understood and readily carried into effect reference may be had to the accompanying drawings which illustrate a conven1ent'embodiment, on which drawings j Figure 1 is a'plan of the back coverj'with parts broken away to show the mechanism infthe interior thereof Fig. 2 is a transverse section, drawn to an enlarged scale, on

line 22 of Fig. 1; but in this view the chain 15 is not illustrated so as to present-a gClGttI illustration of the endless band. Fig.

3 is a part sectional plan view of the front cover; a 1

The covers or backs 1 and 2 comprise clamping bars 3 and 4 pivotedthereto, the

a lower clamping bar- 4 having journaled therein a rod 5'rotatable'for adjusting the clamping bars in relation to one another. A

back or loose strip 6 is passed around the I clamping barsand the ends of such, strip pass into cavities or chambers in the covers 1 and 2.- This strip isvso connected to the rod 5 that when the latter is operated to adjust the' clamping'bars, such strip is correspondingly adjusted so as always toibe'a Specification of Letters Patent.

good fit around the clamping bars. As illustrated one end of the strip 6 is connected to an endless band 7 operated from the spindle v5 to effect which operation the endless band 7 for the Whole or for a portion of its length (preferably the latter) is comprised of a length of chain 8 which gears with asprocket wheel 9 fixed to the spindle 5, the

remaining portion in the case of a part chain band being formed of a strip of 'tex tile material which passes around a roller 10 secured. in relation to the forward'end of the cover. This roller 10 is resiliently mounted such as by the endsthereofbeing fitted within slots 12 of the mounting 13 and being connectedfto springs 14 tending to ini crease the distance between the roller 10 and spindle, 5, whereby the endless band is i always maintained in a taut condition. I Thus when the cover of the illustrated binder'is opened the band is still maintained in a taut condition as the roller is moved by the spring along the slots to counterbalance the reduction in distance between the roller 10 and spindle 5 which would normally be caused in virtue of the cover hinge plates 11 having pivotal connection to the clamping bars at a point which lies to one side of the aXis of the spindle 5, as shown in Fig. 3;,

The clamping bars are conveniently adjusted bychains 15 detachably secured to clamping bar. 3 and'engaging with sprocket ,wheels 16 secured to the spindle 5 which is v j ournaled in theother clamping bar 4. Thus it will be seen that by rotating the spindle 5 inone direction the clamping bars Will be drawn together by the engagement of thesprocket wheels 16 and chains 15, while by the engagement of the chain 7 and sprocket ;wheel 9 the end 6 of the loose or back strip 6 will be drawn into the cover a correspond ing extent thus keeping the. back strip a good fit around the clamping bars. Upon rotating the spindle 5 in the reverse dlrection the length; of backstnp passing out from the covers is increased to the same amount as the increase .of the length, of chain between the clamping bars. It will be seen that the use of the back strip 6 does not preclude the clamping bafrs being moved a sufficient distance apart to permit the looseended sheet-registering leather thongs 23.be.-'

ing disengaged. fromthe cover 1 for-the removalof sheets therefrom or I replacement thereon1- in; j

.To look the S am, ,s-a'ganst rbta i n an i i appropriate means may be employed, and conveniently a multiple disk friction clutch such as set forth in English Patent No. 2971 of 1912 may be employed.

In order that the chains 15 may be prevented from sagging the ends passing into the cover 2 are secured to the end 6 of the strip 6, and as they are thus secured in relation to the endless band 7 such ends are given a movement equal to that imparted to the chains by the sprocket wheels 16, thus preventing the links jamming between the clamping bar a, and cover 2. The end 6 01 the strip has secured thereto a metal plate 6 which providesa convenient means of securing the chains 15 and endless band 7 to the strip 6, and also for maintaining the edge 6* thereof parallel to the edge of the cover 2.

The end (i of the back strip 6 is preterably resiliently secured in the cavity of the cover l'such as by means of the spring 19 located around the rod 20, and between the head 21 thereof and the guide 22 fixed to the cover, said rod 20 being secured to the cover. This spring 19 thus always draws the end 6 of the strip into the cover to thereby maintain tight fit of the strip around the clamping bars, andserves to take up slackness when the binder is opened.

Registration of the sheets is conveniently effected by loose ended longitudinally flexible and transversely relatively rigid members 23, arranged through the clamping bars and terminating without fastening in one or both of the covers.
